Therm-a-Rest Boost 650 20F/-6C Sleeping Bag Morning Blue Long/Wide 14206. As a spacious semi-rectangular sleeping bag the Boost provides all the room you need to side sleep shift about spread out and relax. The semi-rectangular shape gives you considerably more internal space than a mummy bagyoull feel unrestricted and free to sleep in whatever position you want all night long. But more space demands more body heat to warm it up and cold isnt comfortable. Thats where WarmZip comes in. Zipping up the WarmZip center zipper transforms the shape of the Boost 650 from a semi-rectangular bag to a thermally efficient mummy bag.
